  • 摘要: 該文提出一種新的基于OFDM符號寬度的感知方法。該方法首先對接收到的每個OFDM符號在其符號周期內(nèi)進行循環(huán)自相關(guān)函數(shù)的估計,然后利用多元統(tǒng)計理論計算判決量和判決門限,最后將判決量和判決門限進行比較從而得到判決結(jié)果。該方法是非參數(shù)化的,因而能夠在噪聲不確定的情況下有效工作,并且該方法能夠極大簡化目前循環(huán)平穩(wěn)感知類算法的復雜度而只有細微的性能損失。此外,該文接著又提出一個非參數(shù)化多天線線性加權(quán)合并感知方法。仿真結(jié)果表明,所提合并方法通過合理地非參數(shù)化優(yōu)化加權(quán)系數(shù),與傳統(tǒng)循環(huán)平穩(wěn)感知方法相比,在復雜度顯著降低的同時,性能幾乎與傳統(tǒng)循環(huán)平穩(wěn)感知方法一致。
